Wii Fit being a joke could very well be the case.. either way I'm going to go into E3 expecting that to be the big title that they show alongside Wii Sports Resort, Pikmin 3, a suprise or 2 like maybe Kirby or Paper Mario or something cool and then show case Spirit Tracks, Red Steel 2, Grand Slam Tennis and games like that.
If Wii Fit Plus isn't there and instead they have a few more core games or a really big core game or perhaps a new entry in the Wii series then I'm going to be suprised and not disappointed at what they do show.
We'd all love them to show off Retro's new title, NSC's new title, Zelda Wii, Kirby Wii, PilotWings, Mario Galaxy 2 etc etc but seriously :P It won't happen
